The color values of ppm and pgm images can be either 8 or 16 bits.
They can also be scaled to a smaller max value, and they can be
expressed either binary or ascii. For some of these permutations, Qt's
image handler lacked implementation or would decode the wrong color
value. This commit fixes that.

Embeddeding a QWindow via QWidget::createWindowContainer() fails to
deliver the SurfaceAboutToBeDestroyed event. This breaks any OpenGL
or Vulkan based QWindow that releases resources upon this event, and
is particularly critical with Vulkan where the only way to do properly
ordered swapchain - surface cleanup is via this event.
In the non-embedded case close() eventually ends up in an explicit
destroy() in QWindow. In the embedded case destroy() only gets called
from ~QWindow. This then silently breaks since the subclass' reimplemented
event() virtual is not getting called anymore.
To remedy the problem, simply add an explicit destroy() to
QWindowContainer.

The platform plugins reading this out of the QWindow was a layering

A foreign QWindow is created via the factory function fromWinId(),

plugin as function arguments, where the platform will create a

Calling setScreen() on a QWindow doesn't move the window to that screen
unless the new screen is a separate virtual desktop, as the window
geometry is what determines the position of the window within each
virtual desktop.
But when mapping a QWindow that doesn't have a position explicitly set by
the user, we try to resolve a reasonable position for it. In that case we
should take the QWindow screen into account, as setting it to a non-primary
screen is a good indication that the user wants the window to end up on
that screen. If that's the case, it should override the logic of using
the transient parent or the cursor position to choose which screen to
place the window on.

This fix exposed bit-rot in qdrawhelper where qt_memfill32 was set as
a function pointer despite not being one since Qt4.

The regression was introduced in d8857f21ac. The original change was
meant to fix support for SVG icons, but failed to take into account
a valid QIcon with no sizes, but which is also unable to create

This causes the blocked handling in Active Qt to no longer be triggered.
Fix this by iterating over the list using the same condition as before,

This change allows painting via QPainter onto a QOpenGLWindow, QOpenGLWidget
or QOpenGLFramebufferObject when an core profile context is in use. This is
important on macOS in particular, where compatibility profiles are not
available, and so the only way to use modern OpenGL is via a core profile
context.
Added core profile compatible shaders with moder GLSL keywords.
The paint engine binds a VAO and two VBOs from now on, whenever VAOs are
supported. Note that this changes behavior also for OpenGL 2.x context that
have VAO support via extensions.
The Lancelot test suite gains support for core profile contexts. This can
be triggered via -coreglbuffer in place of -glbuffer when manually inspecting
via 'lance', while tst_lancelot will automatically run core context-based tests
whenever supported.

The following is safe:
QOpenGLVertexArrayObject *vao = ...
vao->create();
switch the current context
delete vao;
because the QOpenGLVAO dtor recognizes that the wrong context
is current, and will temporarily restore the VAO's associated
one in order to safely destroy the vao object.
However, the following has been problematic:
vao.create();
switch the current context
vao.destroy();
simply because all the logic was in the dtor and destroy()
blindly deleted the vao object in whatever context was current.
This can lead to releasing a completely unrelated vao object
that happens to have the same name in another context.
The expectation is for context-dependent wrappers is that a
ctor-create-dtor-ctor-create-dtor-... sequence is equivalent to
create-destroy-create-destroy-..., so move the safe cleanup logic
from the dtor to destroy().

The original implementation is only suitable as long as the only client
is the GL paint engine which will call the function with the GL context
current. In other cases this cannot be ensured. For instance, doing
triangulation on the gui thread in a Quick application using the threaded
render loop will have to deal with not having a current context on that
thread at all. Doing triangulation on worker threads has the same problem
as well.
In addition, in modern Qt versions a -no-opengl build does not imply no
accelerated graphics API.
Therefore, drop the ElementIndexUint check from qtriangulator.cpp and leave
it up to the caller to tell if uint indices are supported or not.

Expose that information as QScreen properties.
A use-case for this feature is a Wayland compositor that maps screens
to Wayland outputs hence it needs to replicate the information.
This information can also be added to the diagnostic output of qtdiag.
